After Effects CS5 (MAC, german trial version) needs 5-10 minutes to start up, hangs on the message "MediaCore wird initialisiert". On another Mac (small macbook!) it works fine. I did a reinstall, no effect. No plugins are installed.

Seems the Adobe QT32 Server causes the problem. It is started along with every app. Together with After Effects ist freezes the system ... if I kill the task, after effects starts without any problems.

Is there any workaround, for example can I block the starting of QT32 together with AE ?

I have the same problem, but on Windows 7 Enterprise x64. (German Trial, too.) When i kill the task "Adobe QT32 Server.exe" it won't work! After Effects didn't start, never! I can wait 20 Minutes and nothing happends.

What are the versions of Mac OSX that you're using, both on the computer where After Effects is hanging and on the computer where it is working fine?

You shouldn't kill the Adobe QT32 Server process while After Effects is running. After Effects relies on that process to use QuickTime files. However, it may be the case that this process keeps running when you quit After Effects; in which case you should kill the process before you restart After Effects.

I have the CS5 Master Trial installed on a Macbook Pro 13" with Snow Leo 10.6.3 - After Effects starts within seconds.

The second computer is an iMac 3.06Ghz 24" with Quicktime 7 Pro installed (and Quicktime X). Same Snow Leo 10.6.3. Every app from the master pack starts very fast, only After Effects needs 5-10 minutes which is caused by the QT32-process. The process comes up within After Effects, he is not running prior to starting AE. If I kill the process immediately after start, the start sequence of After Effects is starting again and is finished within seconds.

I tried everything, including a complete reinstall and using onyx to clean up the mac itself... no result.

By the way: in activity-monitor I can see that the QT32 seems to hang on "vnode: FD unavailable" ever and ever again... but I don't know if that's important

Another question: why starts premiere pro cs5 without any problems using that same qt32-process? Starting after effects, the qt32-process causes 5 minutes pausing, starting premiere pro theres no problem. What is the difference between the AE-qt32 process and the PPro-qt32-process?

After Effects uses TCP to communicate with the QuickTime server (Adobe QT32 Server) and the Dynamic Link manager, but we limit the connections to the local machine only (which is enough for most firewalls).

If you are having problems with After Effects hanging in communication with either of these processes, then explicitly telling your firewall to allow them to communicate may help.

Which port do we need to open up to let AE communicate with QT32 Server? AE hangs on my desktop machine, but opens up perfectly on my laptop. I'm not aware of any difference in networking settings between them.

I'm having the same problem and it's really starting to frustrate me. AE (Cs5) hang son start-up until I kill the "Adobe QT32 Server" process. But if I do that I can't dynamiclink or export in any QT format. I can open Premiere Pro (Cs5) or any other Cs5 program just fine. I've tried deleting the preferences thing, tried reinstalling, and a few other things but no luck. I have a Macbook Pro 2.88ghz C2D 4gb ram with 10.6.3 and QT 7 is installed. Please fix this Adobe.....

I have a Mac... I don't have a firewall. I have a program called Little Snitch that is the closest thing to a firewall, it's a network traffic monitor. But even when I disable it After Effects doesn't work.... The only way right now that I can get AE 10 to open is by quitting the "Adobe QT32 Server" process and as I stated before, it jacks up my workflow in After Effects... I have pretty much tried anything and everything that has been listed about this topic on these forums: deleting preferences, reinstalling After Effects, creating a separate user, etc... I think until Adobes finds a fix for this shenanigan I am just going to stick with AE 9...

AE and Pr both use separate copies of the QT32 Server when running. This is normal. If both apps are running at the same time it may not be clear which QT32 Server is which. You may want to avoid that while investigating these issues.

Some of you appear to be having different problems. Let's keep this thread focused on QT32 server related hangs only. Please start a new thread if:

1. you are never seeing an AE splash dialog come up

2. the splash dialog does not say "Initializing MediaCore" during the hang you are seeing

3. killing the QT32 Server process in the Activity Monitor (mac) / Task Manager (windows) does not result in unfreezing AE.

Please note that if the Activity Monitor says QT32 Server is "unresponsive", that can be normal and does not, by itself, mean you are experiencing a QT32 Server hang problem. If (2) is happening but not (3), then you are likely experiencing some other plugin related issue than the QT32 server. If all the above do apply to you. Make sure you've tried the firewall fix mentioned above first.

If that doesn't help, on Mac please get the following information: Repeat the hang with only AE running, then go to the Activity Monitor and select the QT32 Server process. Then press the "Sample Process" button at the top of the window. When the sample is complete, please post the first page of the resulting text file.

Thanks guys. It looks like both of you are having a similar problem with a third party AVI codec. Please remove or uninstall any third party AVI codecs such as DivX, XVid, etc. from your system and try AE again.

You can also temporarily disable these components by closing any QT related apps and then dragging components out of the Library/QuickTime folder on your boot drive. If that works, try adding them back one by one until it fails again. That is the problem codec.

Thanks for your help figuring this out.. and for the beer offer. Don't think I'll be in Dresden any time soon, but if you could recommend a brand I'll give it a try here.. hoist a virtual toast as it were

Just for the record, this would appear to be caused by the Perian codec for Mac, correct? Which version was causing this problem? Thanks.

This particular QT32 Server problem is only about third party QuickTime codecs. Are you still having a hang problem on AE startup that matches the three criteria listed in a previous post? Are you on Mac or Windows?

You would have non-standard QuickTime codecs only if you either:

- installed them yourself (like the Perian codec), or

- they were installed by side effect when you installed other video applications or hardware

Seth no this was not caused by the Perian component (for me anyway). It was an AVI Importer component.... I have also had problems with After Effects on other computers and these problems were caused by bad fonts on my system so I suggest to others to check that if they are having problems too...

I'm running AE CS5 on Windows 7 (64 bit). The program worked fine for months but is now hanging up on start up during the Initializing MediaCore sequence. It takes about 5 minutes to launch the program and when it finally does I get the following error message:

You have at least one output module template that refers to a missing output plug-in. Please check your Output Module Templates.

It seems to have lost the Quicktime codec and now will not recognize any files in the Quicktime format.

That document talks about aggressive firewall settings, but we've also seen that some other software (like FileMaker) can block the TCP communication that these components require.

If I'm right about what's causing the problem, the QuickTime failure is because After Effects is being prevented by some software on your computer from communicating with the Adobe QT32 Server process.
